hmmm.... if they're the same system, the same hw and the same confs |
| 48 |
it's impossible for them not to work. try to see if by chance you |
| 49 |
don't have dhcpdb or networkmanager started on the second os at boot. |
| 50 |
the only thing that might prevent static routes from working is that |
| 51 |
some dhcp is starting before setting the static net.ethX interface. |
| 52 |
see the dmesg and the system log in search of the ethX problems. if |
| 53 |
the 2 oses are exactly the same then there's no reason for them not to |
| 54 |
work in the same way. you'll just have to remember that maybe the |
| 55 |
router is caching the ethernet entry and might not allow the use of |
| 56 |
another static ip on the same mac. have a look inside your router |
| 57 |
configuration and see if it caches or binds addresses. usually |
| 58 |
commercial routers do this until reboot. |
